(after Framenau & Castanheira, 2022) Larinia tumulus is by far the smallest Larinia species in Australia (body length males < 3 mm, females < 4 mm; all other species: males > 4 mm, females > 5 mm (Framenau & Scharff 2008). The median apophysis of the male pedipalp is unique amongst Australian species with two spine-like dorsal prongs; most similar is L. sexta but the prongs in that species are much stronger. Similarly, the large, ovoid, flat epigynum is unique amongst Australian Larinia, that of L. sexta has a much more pronounced median septum.

Fauna Portal Records
The map shows all records that have been verified as part of the Fauna Portal project and may not represent the true distribution of a species. Specifically, for described species, check the link to the Atlas of Living Australia on this page for potential wider distributions. Fauna Portal Reference specimens and Linnean types are shown in red. If you identified a specimen that exceeds the distribution of an undescribed species as illustrated here, please contact the Fauna Portal team who can assist with the lodgement of the specimen in a public institution and display on the map.
